Experimental Study On Performance Of Perma Zyme Stabilized Soil

With the rapid development of highway construction,the amount of Sand,stone and other building materials has become increasingly,which become scarce,its exploitation of damage on the natural environment is also more and more serious,therefore,Continued development and use of new building materials to substitute for sand and gravel achieve the dual purpose to solve the problem of shortage of natural sand and gravel,save investment in construction and protect the environment.Due to low intensity of soil,glial component of the expansion and contraction and other reasons,can not be used directly in the path layer of the pavement structure.PERMA ZYME curing agent is a biological pollution-free soil curing agent,used PERMA ZYME curing agent and cement to increase intensity,stability,shrinkage and other pavement performance of the soil.Mechanical properties,stability performance,shrinkage property and other pavement performance of PERMA ZYME solidified soil is evaluated by unconfined compression,split, bending tensile,compression rebound modulus,bending tensile modulus,cyclic wetting and drying,freezing and thawing resistance,shrinkage and temperature shrinkage test,analysis the intensity and stiffness of PERMA ZYME solidified soil,water stability,crack resistance and other pavement performance,and put forward to reasonable mix proportion.Sent study shows that PERMA ZYME solidified soil can meet the technical requirements of highway roadbases, can be used as light traffic roadbases or heavy traffic subbase.It is the practical significance to promote the application of non-polluted solidified soil to protect the natural environment along the highway,to solve part of shortage of gravel roads Materials,to reduce highway construction costs.
